WHAT IS THE INTEGRATED
TRAILER BRAKE CONTROLLER
The trailer brake controller assists in
smooth and effective trailer braking based
on the towing vehicle
’s brake pressure.
INTEGRATED TRAILER BRAKE
CONTROLLER PRECAUTIONS WARNING: Use the integrated
trailer brake controller to properly adjust
the trailer brakes and check all
connections before towing a trailer.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
• Only use the manual control lever for
proper adjustment of the gain during
trailer setup. Misuse, such as
application during trailer sway, could
cause instability of trailer or tow
vehicle.
• Avoid towing in adverse weather
conditions. The trailer brake controller
does not provide anti-lock control of
the trailer wheels. Trailer wheels can
lock up on slippery surfaces, resulting
in reduced stability of trailer and tow
vehicle.
• The trailer brake controller is only a
factory-installed or dealer-installed
item. Ford is not responsible for
warranty or performance of the
controller due to misuse or customer
installation.
Note: Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result. USING THE INTEGRATED
TRAILER BRAKE CONTROLLER
1.
Make sure the trailer brakes are in good
working condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred. Your
vehicle warranty does not cover issues with
your trailer.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions.
Note: Select default mode if the trailer has
surge brakes, or no brakes at all. The system
has no effect on the braking performance
of the trailer in either of these cases.
Note: If a trailer is connected by a four-pin
connector, the trailer braking function will
not be supported.
3. When you plug in a trailer with electric or electric-over-hydraulic brakes, a
message confirming connection
appears in the information display.
4. Use the gain adjustment to find the desired starting point. A gain setting of
6.0 is a good starting point for heavier
loads.
Note: Use the following steps to adjust the
gain setting whenever road, weather and
trailer, or vehicle loading conditions, change
from when you initially set the gain.
5. In a traffic-free environment, tow the trailer on a dry, level surface and
squeeze the manual control lever
completely.

(If Equipped)

6. If the trailer wheels lock up, indicated
by squealing tires, reduce the gain
setting. If the trailer wheels turn freely,
increase the gain setting. Repeat Steps
5 and 6 until the gain setting is at a
point just below trailer wheel lock-up.
If towing a heavier trailer, trailer wheel
lock-up may not be attainable even
with the maximum gain setting of 10.
Note: Only perform this procedure at
speeds of approximately 20– 25 mph
(30–40 km/h).
Note: The trailer brake controller reduces
output at vehicle speeds below
11 mph
(18 km/h) so that trailer and vehicle braking
is not jerky or harsh. This feature is only
available when applying the brakes using
your vehicle's brake pedal, not the
controller.
Note: Your vehicle's brake system and the
trailer brake system work independently of
each other. Changing the gain setting on the
controller does not affect the operation of
your vehicle's brakes whether you attach a
trailer or not.
Note: With the proper electrical connection,
pressing your vehicle brake pedal or using
the manual control lever illuminates both
trailer and vehicle brake lamps.
Note: When you switch the engine off, the
controller output is disabled and the display
and module shut down. The controller
module and display turn on when you switch
the ignition on. Adjusting the Trailer Brake Gain
Increase or decrease the amount
of gain in set increments.
A
Slide the control to engage the
trailer brakes.
B
Note: Adjust gain setting before using the
trailer brake controller for the first time.
Note: The gain should be set to provide the
maximum trailer braking assistance while
making sure the trailer wheels do not lock
when using the brakes. Locked trailer wheels
may lead to trailer instability.
Note: Setting adjustments are saved when
a trailer profile is selected.
Note: If you have installed an aftermarket
trailer brake controller in addition to the
integrated trailer brake controller, set the
gain on the integrated trailer brake controller
to zero.

HOW DOES TRAILER SWAY
CONTROL WORK
The system applies the brakes to the
individual wheels and reduces engine
torque to aid vehicle stability.
If the trailer begins to sway, the stability
control lamp flashes and the message
Trailer Sway Reduce Speed appears in
the information display.
Stop your vehicle as soon as it is safe to
do so. Check the vertical weight on the
tow ball and trailer load distribution.
TRAILER SWAY CONTROL
PRECAUTIONS WARNING: Turning off trailer sway
control increases the risk of loss of
vehicle control, serious injury or death.
Ford does not recommend disabling this
feature except in situations where speed
reduction may be detrimental (such as
hill climbing), the driver has significant
trailer towing experience, and can control
trailer sway and maintain safe operation.
Note: This feature only activates when
significant trailer sway occurs.
Note: This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple
times, gradually reducing vehicle speed.
SWITCHING TRAILER SWAY
CONTROL ON AND OFF

Note:
Your vehicle has two options for the
trailer reversing aid setup. If your vehicle
came with a trailer sensor kit or if a message
displays to install a sensor, follow the sensor
installation instructions. See Trailer Sensor
Installation (page 448). If your vehicle did
not come with a trailer sensor kit, follow the
sticker installation instructions. See
Applying the Trailer Reversing Aid Sticker
(page
448).
Note: If your vehicle came with a trailer
sensor kit, the vehicle will receive an update
that allows the system to operate with a
sensor or sticker. If your vehicle did not come
with a trailer sensor kit, your vehicle can be
setup using either method, but you need to
separately purchase the trailer sensor kit
from your authorized dealer.
APPLYING THE TRAILER
REVERSING AID STICKER
Place the sticker in an area visible by the
rear view camera. The entire sticker must
be within
4– 19 in (10–48 cm) from the
center of the hitch ball, as shown in the
following illustration. Use the supplied sticker placement card,
a tape measure and pen to carefully mark
the area to attach the sticker. The sticker
is in the back cover pocket of your quick
start guide. Make sure the entire sticker is
within the green zone between the two
arcs or distance markers on the diagram,
and is also visible in the rear view camera
display.
Once you have found the correct location,
place the sticker.
Note:
Make sure nothing can obstruct the
rear view camera's view of the sticker such
as a jack handle or wiring.
Note: Position the sticker on a flat, dry and
clean horizontal surface. For best results,
apply the sticker when temperatures are
above
32°F (0°C).
Note: Do not move stickers after placing
them. Do not re-use any stickers if removed.
Note: You can purchase additional stickers
through your authorized dealer.
Note: If you previously setup the trailer with
the trailer sensor, make sure it is not plugged
in before configuring the trailer and placing
the sticker.

Note:
The touchscreen shows if you are
going too slow or fast. Calibration pauses if
the speed is outside the required range of
2 –9 mph (4– 15 km/h).
Note: You need to complete at least a 90°
turn, and longer trailers could require a 180°
turn. Camera trailer tracking requires the
system to locate the hitch ball as well as
determine the trailer length. Some trailers
could require you to drive straight then turn
multiple times before calibration completes.
The touchscreen provides instructions and
notifies you when calibration completes.
Note: For best results, do not calibrate the
system at night when calibrating the system
with the sticker.
SWITCHING TRAILER BACKUP
ASSISTANCE ON AND OFF Press the button and use the touchscreen
to select the connected trailer. Note:
A trailer must be configured to use
trailer backup assistance. See Configuring
the Trailer (page 446).
Note: If you use the steering wheel when
using trailer backup assistance, the system
turns off and a message displays in the
touchscreen.
Note: If the trailer was connected just prior
to turning the system on, you may need to
drive forward to initialize the system. Follow
the instructions on the touchscreen to
activate the system.
USING THE TRAILER BACKUP
ASSISTANCE CONTROLLER
Use the control knob to steer the trailer.
Take your hands off the steering wheel and
turn the control knob instead. The control
knob acts as the steering control for the
trailer. Turn and hold counterclockwise to make
the trailer go left.
